YOU MUST follow these steps :
1) First boot will delay a few minutes
2) IMPORTANT: Go to BIOS Setup ( F10 ) and reset to Factory Default (first main page tab)
3) Restart and enter BIOS
4) 2nd boot restore security settings to defaults

The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
use BCU and put your original DMI.
